buy 10 normal discs and just copy data from one to other every 2 years

>>25653525 dont want to go into the reasons but wont work for me

>>25653514 how much of cp do you own?

SSD will lose data without power in a few years

Listen, if you're storing it away, the SSD will start losing data after half a year disconnected.

>>25653537 not a pedo >>25653539 >>25653542 Would a HDD work?

>>25653546 In theory. In practice you might not get it running in 20 years. Inside there are plenty of components that can age just from sitting around.

>>25653552 In that case, could I move out the magnetic disks, and put them in a new HDD?

>>25653546 >not a pedo what youre hoarding is not worthy of advice theb

>>25653569 you work for the fsb

>>25653567 Listen, the idea is just fucking retarded. Store your data with backups you maintain.

>>25653574 It has to be a time capsule.

>>25653583 Print it out.

burn it on a dvd disc

If it is a lot of data, maintain it. Everything has to be maintained or it starts crumbling.

>>25653594 You never heard of disc rot?

flash devices can't be trusted to last, they're too easy to manufacture sloppily hard drives have to be built with extreme quality control to get them to work at all, if they're for external use being kept in a drawer their bulkiness and non-drop-safety aren't issues and they are clearly the superior choice only an idiot would buy a terabyte drive when two 500gb drives can be gotten for a tenth the price I am not a paedophile either btw

>>25653614 >hard drives have to be built with extreme quality control to get them to work at all hahahhahahahaha look and laugh at this nigger

>>25653594 Would that work? >>25653596 I dont want to go into the reasons, but I want to keep it with a friend, and I dont know if they can be relied on to maintain it. Maybe I can explain the process to him.

> that can last for at least 20 years Its don't. You're looking at specialty hardware here (tapes or optical media, and not the kind you've dealt with before). What are you trying to achieve?

>>25653614 >only an idiot would buy a terabyte drive when two 500gb drives can be gotten for a tenth the price Are you posting from 2010 or what

>>25653638 Time capsule for some personal data. I will keep it with a friend because I dont want to look at it for a long time.

>>25653649 You have no options that aren't professional grade and with acceptable risk profile. There is no technology for large amounts of data that lasts twenty years without someone knowledgeable taking care of it. Best bet is to find a company that specializes in long term data storage and take a 20 year contract.

>>25653656 >>25653649 More specifically, archive grade optical media exists but it's exotic and not something you've heard of, or want to afford. This for example: https://pro.sony/en_HR/products/optical-disc Tapes exist but drives are expensive and they want to be stored properly (with temperature control). And you better have some way of getting a working drive 20 years down the road, and have it be compatible with whatever tape you have.

I've heard good things about rsync.net though. Or god forbid amazon.

>>25653616 shut up, making a hard drive that will work for a few months then fail IS much harder than making a flash drive that will work for a few months then fail >>25653642 hmm prices have changed since I last looked 2x 500gb is still the better deal though

>>25653514 >>25653583 >last for at least 20 years >time capsule M-Disc Blu-ray might be the best storage option with requirements like that. I really can't think of any storage option that is readily available and beats M-Disc Blu-ray in longevity. Every now and then, there pops up news about some new storage technology offering to store huge data amounts for 1000 years, but real products remain elusive. https://en.wikipedia.org/wiki/5D_optical_data_storage https://en.wikipedia.org/wiki/3D_optical_data_storage https://en.wikipedia.org/wiki/Holographic_Versatile_Disc

>>25653726 500 GB HDD? Obsolete basically. 500GB SSD? Nearing obsolete, and a 1TB SSD is 50 bucks these days.

>>25653674 >https://pro.sony/en_HR/products/optical-disc Nearly all products on that website are listed as "Discontinued".

>>25653752 yes, much too much

>>25653760 Yes. I posted it for completeness, not as recommendation.

>>25653583 well, whatever you choose, don't put everything in one basket add some error correction and redundancy even if you lose some, most might still be readable check for blurays for archiving / tapes

>>25653740 >I really can't think of any storage option that is readily available and beats M-Disc Blu-ray in longevity. DM for Archive BD-R

Danke you all for your advice. I will see if a blu-ray disk will work. Do I have to burn my data to the disk permanently? Is it possible to encrypt data this way?

>>25654059 >Do I have to burn my data to the disk permanently? Read-only discs are longer lasting than discs with read-write capability. >Is it possible to encrypt data this way? Yes, you simply encrypt the data, the encrypted data/files are burnt to disc.

Just buy a normal hard drive and put it in a case with SATA connector that costs like $5

>>25654223 you don't need an enclosure, just an adapter

What's the use case of an external drive? I've never used one and never saw need of one

>>25653546 HDD holds data for longer, but for cold storage optical media is your only choice.

>>25655031 >It's a product for people who actually leave the house. You wouldn't understand

>>25653546 >not a pedo Of course not, you're just collecting CP for research reasons, as we all are.

>>25654059 danger of rotting. Make sure you research proper storage conditions. https://en.wikipedia.org/wiki/Disc_rot

>>25655112 I can take out my disk and leave the house with it, if I ever needed that.
